The nature of my invention consists in so modifying the shoemakers heel plane or shave that he can use it with equal, and indeed greater, facility upon the edge of the front part of the boot or shoe.

Figure 3 is a perspective view ofthe instrunient, the handles A being of wood, the other parts ofmetal. Thehandles may be ofthe saine. all parts except the knife or cutting part being verypractically cast from malleable iron. Fig. l and Fig. 2 represent sections of the instrument, of medium size.

The sides B B curve down about an inch, and are connected by G G', which in fact are B B continued. As B B curve down, they also extend back, increasing the lower surface of C, between which and C there is an opening,

as shown at G, Fig. 2, and extending across from B to B.

D D represent lips t,extending below the under surface of C C. In each of these lips, and immediately below the lower surface ot' C C', a groove is cut and occupied with the knife E and a metallic plate, H, which is fitted to the under surface of O, and nearly as thick as the knife. C is also thickened at the center, through which the thumb-screw F is inserted, its lower end pressing against the beveled sides ot' a hole in I, a piece of metal working against the knife E. Y V

By the screw the knife can be kept at any point, and as it is moved forward and back the depth of its cutting is regulated.

fhatlclaim as my invention, and desire to secure by Letters Patent, is-

1. The construction of the grooved lips D D immediately beneath the surface of C, substantially as set forth. 4

2. Thecombination of the knife E and the screw F with the grooved llps l) D, substantially as set forth.
